Appnanonnieaneeembere, 190s. seriai No. 183,578.

county of Middlesex, State of` Massachusetts,

have invented a certain new and useful Imrovement 1n `Wool-V17 ashingV Machines, of

which the following is a 'specilicatiomreferv ence being had therein to the accompanying drawings,

The invention relates tothe means vfor actuating the harrows by which wool or otherV material under treatment is moved along within the bowl of a wool washing machine or other like machine.

We have shown the invention embodied in a machine containing some of the features which are shown :and described in United States Letters Patent for wool washing ma chine, No. 67 5,069, granted to F. G. Sargent May 28, 1901.

Having reference to the drawings,-Figure 1 shows in side elevation the main portions of a woolwashing machine having kthe invention applied thereto. Fig. 2 shows thesaid machine in longitudinal vertical section on line 2, 2, Fig. 3. Figi?) shows the machine inplan. y

llromV the drawings we have omitted ccr tain of the details and accessories of themachine which are not involved in the present invention.

rThe bowl of the washing machine is desig-` nated 1. The usual false bottom separating the upper and lower portions ofthe interior space of the bowl from eachother, and perforated to permit of the passage therethrough of the liquor which is introduced into the bowl, is shown at 2, Fig. lt is omitted from Fig. 3 in order to show the arrangement of pipes in the lower portion of the bowl for drawing-off the liquor. The u wardly inclined extension of the vsaid fa se bottom, located at the delivery end ofthe bowl, and up which the wool or other: material under treatment is passed in discharging itfrom the bowl, is marked 21. 1

A harrow of usual character is shown at 3, it being provided with teeth 31, 31,as heretofore. The movements of the said harrow in working within the bowl above the false bottom 2 are as heretofore, it being advanced lengthwise within the bowl for the purpose of pushing forward therein the material under treatment, then being raised at the conclusion of its advancing movement so as to withdraw l' its teeth the said material, being then returned above the said material toward the receiving end of the bowl, and being then lowered to cause its teeth to rengage with the material contained in the bowl, the movements being repeated in regular succession. v .e

As in the Letters Patent of May 28, 1.901, aforementioned, the sides 0f the bowl are provided turned ends, and rollers 12, 12, are mounted upon the cross-rods 13, 13, which are attached to the harrow, the said rollers coming to rest upon the saidtracks as the harrow descends from its elevated position into the bowl, whereby Vthev harrow is sup orted in its lowered vposition within the owl, the said rollers traveling along the tracks during the advancing movement of the harrow. So also, the weight of the harrow is partly counterbalanced and its opposite ends are caused to rise and fall in unison, as in the said patent, through the employment of the rock shafts 7, 7, extending transversely through pipes or tubes extending across the lower portion of thebowl from side to side of the latter, each of the said rock-shafts having at its opposite ends arms, as 71, which are connected by means of connecting rods 72, with the opposite ends ofthev cross` rods 13, 13, each rock-shaft 7 having an arm with tracks 11, l1, having up` 73 carrying a weight 74. The rock-shafts f 7, V7, of the counter-balancing mechanism are connected so as to cause them both to move in unison, as in United States Letters Patent No. 521,823, granted to F. G. Sargent June 26, 1894, by means of an arm 75 upon each of the saidl rock-shafts, and atrod 76 joining the arms 75, 75, with each other. The means of actuating the harrow, for the purpose of communicating thereto the various movements to which reference has been made hereinbefore, will presently be explained.

A carrier, by means of which the wool or other material that has been advanced by the harrow to near the discharging end of the bowl is caused to pass up the inclined extension 21 of the false bottom, is represented at 4, it being provided as usual with teeth 41 for vengagement with the said material.` The carrier 4 is actuated through connections with the rotating crank-shaft 42, which latter is mounted in bearings in small standards 43 rising from the sides of the bowl, the crank or cranks of the said crankreceiving end ofthe bowl, as shown in Fin'. 1

shaft 42 having connected therewith the side-bars 44 of the carrier-frame, the said carrier-frame being provided at the end thereof adjacent the squeeze-rolls, and at opposite sides of the machine, with rolls 45 Working on inclined tracks 46, all being substantially as heretofore in like machines.

Y 5, 5, are a pair of squeeze-rolls, receiving the material as the latter is fed b f the carrier 4 from the discharging end of the bowl, and serving to express therefrom the liquorl with which it is saturated, the expressed liquor being received by the tank 6 below the said squeeze-rolls.

The pump for returning to the bowl the liquor which is received by the tank 6 is irdicated at 8, F ig. 1, it connnunicating with the said tanl by means of the pipe S1 and with the bowl by means of a pipe 82, the discharging end of which latter overhangs the so that the liquor therefrom will fall upon the wool or other material at the said end of the bowl. The pump for causing the circulation of the liquor within the bowl is shown at. 9. The said pump 9 communi- Cates with the lower ortion of the interior spaces of the bowl, be ow the false bottom 2, by means of the cross-pipe 92, Figs. 2 and 3, longitudinal pipe 93, and second cross-pipe 94, all having openings for the entrance of the liquid contents of the bowl, and the liquor which is drawn by the said pump from the said portion of the bowl is discharged into the receiving end of the bowl upon the material'at such end, through the pi e 91.

n the machine shown and described in Letters Patent to F. G. Sargent of lliay 2S, 1901, aforesaid, the power connections providing for the actuation of the harrow and the carrier are located entirely above the level ofthe main part of the bowl. A rotating shaft provided with a band-pulley for the reception of driving power, and having operative connection with the harrow, is mounted in bearings which are provided on upwardly extending portions of the sides of the bowl. The connections from the harrow to the said shaft rise above the harrow. This location of the actuating means and connections for the harrow increases the height of the main part of the machine, and interferes with access to certain portions of the bowl.

e present invention has for its vobject to obviate the disadvantages of the arrangement aforesaid of Letters Patent to F. G. Sargent of May 28, 1901, and to provide a better and more convenient arrangement for the same purpose.

In carrying the invention into effect, we arrange the said connections, and preferably also the power-receiving instrumentalities, below the level of the upper edge of the main portion of the bowl. Ne will describe the l l l l l l l l l l l l l l l l l l l l l best arrangement which we have thus far devised with reference to the illustration ol' the same in the accompanying drawings. The main power or driving shaft is shown at 10. To enable it to be located at an intermediate point in the height of the bowl, a pipe or tube is extended across the latter below the perforated bottoni 2, with its ends` secured in the opposite sides of the bowl, and the shaft passes through the said pipe or tube, which is jrn'ovidcd with suitable bearings for the shaft.

'.lo one end of the driving shaft 10 are applied fast and loose band-pulleys 101, or thc equivalent thereof, for the reception of a sui table driving band 102,17`ig. 'l for the transmission of power to the driving shaft from a snilable line or c nmtcrshaft (not shown). Bv means of gearing 1031, 103, 1032, power is transmitted from the driving-shaft 1.0 to the crank-shaft 42 for the purpose of rotating the latter to actuate the carrier. 4.

At 1.041 is the shaft which serves more inl.- mediately in the actuation of the harrow. This shaft, also, is located at an intermediate point in the height of the bowl, and passes through a second pipe or tube 1042 extending transversely across the lower portion of the bowl with its ends secured in the sid of the latter, and provided with bearings to which the shaft 1041 is iitted. The shaft 1041 has applied thereto the means for raising the harrow, supporting it in elevated position and meanwhile moving the same longitudinally tdward the receiving or feeding end. of thc bowl, lowering it, and moving it longitudinally in the opposite direction toward the discharging end. of the bowl. Such means comprises in this instance crank-pins 105, one of which is shown in l? ig. 1, carried by wheels 104 and 1049, which, respectively, are fast upon the opposite ends of shaft 1041, wheel 104 being a gear-wheel in mesh with gear 1031, whereby shaft 1041 is driven from shaft 10. Each crank-pin is furnished with a suitable roller and worhs in a vertical slot 106 of an arm carried by the harrow and extending down therel'rrnn outside the bowl. Each arm is connected with the corresponding side of the harrow in manner rendering it rigid with respect to the direction ol' the length of the harrow. rlhc manner and means of connection may vary, as preferred. by the builder or user of the machine. AIn this instance, the arm is what we term a harp it comprising an upright portion 107 having its upper end fitted to a cross-rod 10S which forms a part of the harrow, and an eX- tension 109 extending obliquely to and connecting with another cross-rod, 13, of the harrow. The oblique extension 109 serves as a brace and tie to stifl'en the depending arm.

In the rotation of the shaft 1041 the crankpins take against the upper ends of the slots 106, lifting the harrow and supporting it, and meanwhile by acting against the forward sides of the said slots they operate to move the harrow toward the feeding end .of the bowl. vThen, lowering the harrow, they act against the opposite sides ol the slots to move the harrow lengthwise toward the discharg` sidev of theharro'w, extending below the top of the bowl, alongside the latter, and rigidly braced to the harrow, anda rotating actuator engaging directly with the lower portion of the said rigid arm below the upper edge of from below, support it from below, communicate lengthwise movement thereto while thus supported, and lower it again.
